Is it possible for two women to combine their eggs in order to have a baby?

No.
You need a male part to complete the set.

That part goes without being said! I know we'll need a donor but we would like both of our genes and physical characteristics in our child! I would just like to know if that's possible?

No. Interesting concept however. Other mammals are capable of it.

No, you can't combine eggs. Look at people who have had children together, we have 4. Different hair, eyes, size, etc. So many variables unless it is identical twins.

Sorry, I mean animals who have litters can have different eggs and multiple fathers.

Although in one human embryo the chromosomes are shared equally, the genes can be very much weighted toward one parent.
